Most 67's i see have the small back window. I dont like them, they are a pain to see out of. My friend had a '67 with the little window...backing it up once made me miss my '72s large window. Also, i think every C40-C60 truck made from 67-72 has the small back window, they are a good source for small window cabs if you want one. Even the 73-87 C40-C60 trucks have the little window. I have wanted to see one of those cabs on a C10, i think a 73-87 with a small back window would look pretty neat
